Abstract: A sealed electrical enclosure used in hazardous locations for enclosing circuit breakers having a bottom housing and a removable top housing with a labyrinth joint or serrated joint formed therebetween, the bottom housing adapted to receive one or more circuit breakers, a first metal bus extending from a point internal to the bottom housing through a first end wall to a point external thereto, and a second metal bus extending from a point internal to the bottom housing through a second end wall to a point external to thereto, where the first and second metal buses are adapted to contact first and second electrical terminals of a circuit breaker when placed within the bottom housing, and a first lug retaining bracket secured to the bottom housing and extending to a position beneath the first metal such that a bottom portion of a connector assembly may fit within the space between the end of the lug retaining bracket and the bottom of the first metal bus.

Abstract: A sealed electrical enclosure for use in hazardous locations for enclosing circuit breakers having a bottom housing and a top housing with a labyrinth joint, a serrated joint, or combination of both being formed therebetween, a first aperture extending through a first end wall of the bottom housing and positioned adjacent a first contact terminal of a first circuit breaker, the first aperture further including a first metal bus extending therethrough and in electrical contact with the first contact terminal, and a second aperture extending through a second end wall of the bottom housing and positioned adjacent a second contact terminal of the first circuit breaker, the second aperture further including a second metal bus extending therethrough and in electrical contact with the second contact terminal, and a first actuating mechanism positioned on the top housing adapted for manipulating a switch of the first circuit breaker.
